T 0 @ZZ ywhom if m/tg/ concern.'

Be it known that I, FRANK P. MILLER, a citizen of the United States, and a resident ot' Downingtown, county of Chester, State ot Pennsylvania, have 'invented certain Improvements in Paper-Making Machines, of which the following is a specification.

One object of my invention is to improve the construction and arrangement ot machines for the manufacture of paper, so that the ground area occupied by the building in which the machine is located will be mavterially reduced.

A further object of the invention is to so design the machine that the drying cylinders will be loca-ted ou a separate floor from the making mechanism and the calendering rolls and cutters.

-A still further object of the invention is to provide means whereby the moisture.y arising from the wet paper being dried by means of the calendering rolls, will not condense anddrop onto the paper being formed or upon the finished paper.

A further object of the invention is to so design the machine that longitudinal air currents will be avoided and `thatthe moist heated air will pass direct to ventilation at the `roof of the building, and that fresh air will be supplied. from the lower floor.

These objects I attain in the following manner, reference being had to the accompanying drawings, in which Figure 1, is a longitudinal sectional view through a factory building, showing the paper making machine, calendering rolls, and the cutting 4machines on the lower floor.

land the drying machines on the upper floor above ythe first mentioned machines;

Fig. 2, is a plan view of the machines on the first door, showing the papermaking and calenderiig rolls and the cutting machines;

Fig. 3, is a plan view of the upper floor, showing the drying cylinders; and

Fig. 4, is a transverse sectional view through the building on the line 4 4, Fig. 1.

In the manufacture of paper and particularly paper knownas box board, which is comparatively heavy andconsists ot a number of plies, the paper, or stock, is ot low grade. The demand now calls for large' quantities, which must be made on extremely large machines having a great width and of such a length that the paper canbe made continuously and received in a dry' condirform desired.

tion at the critters to be cut into the required sheets. Ordinarily,'a machine for accomplishing this purpose is ot great length and occupies considerable floor space. The drying cylinders are located at the center of the building and the making mechanism .is at one end, and the calendering rolls and cutters are at the other end, consequently thc moisture rising from the drying paper on the drying cylinders travels toward each end ot the building and condenses, dropping on the paper being made and on the finished paper.

I have found that I can save about fifty per cent. in the length of a building andcan protect the paper while it is being formed, as well as the finished paper, from the moisture from the drying cylinders, and can carry oii' the` moisture from said cylinders as soon as it is formed by the arrangement I will now proceed to describe.

Referring to the drawings, 1 is the building yin which the machinery is located. 2 is the ground floor. 3 is the floor'of the second story and 4 is the roof which, in the present instance is shown Hat but it may be of any The second floor is discontinued at each end to allow for the passage of the paper to and fromvthe drying apparatus on said Hoor. v

5 is a series of' paper making machines of the cylinder type` in' the present instance.

' each having a vat Gand a making screen of the building is thedrying mechanism 12 consisting of a trarne on which are mounted the drying cylinders 13 and 14. The cylinders 14 are located above the spaces be'- tween the cylinders 13 and the paper passes .around these cylinders in the manner shown in Fig. 1.r These cylinders are of a number suflicient `to dry the paper before itleaves the machine at the opposite end of the building, where it passes down and around the nal cylinders 21 and then around the two sets of calendering rolls 22 and 23, in

the present instance, which give a finish to the paper and press it to the proper degree,

Y. The paper then passes to the cuttingmachine 18, shown in diagram, which slits the sheet lengthwise into the number ot sections desired, and also cuts the sheets transversely. according to the size of the finished sheet desired.

It will be understood that the drying apparatus extends substantially the full length of the second floor ot the building, so that the moisture arising from`the paper being dried will rise to the roof and pass out ot 'the ventilators 15, which are arranged at one side of the root' inthe present instance and extend the full length ot the building.

The Hoor 3, in the present instance, is made in three sections, the central section a is directly under the drying mechanism, While the sections J are above the section o r and at each side of the drying mechanism,

leaving vertical open spaces 16 between the sections so that fresh air from the first floor Will pass up through the open spaces and will pass through the second story to the ventilators 15, as shown by the arrows,` Fig. 4, carrying With it any moist air trom the drying machine.

In order to keep a blanket of warm air at the ceiling of the second floor, I locate a series of steam pipes 17, as shown in Figs. 1 and 4, at the ceiling, so that there is no tendency of the moist air condensing before passing into the ventilators. i

The ventilators` are preferably made as shown in Fig. 1, part ofeach ventilator extends down from the ceiling a certain distance and the ventilator extends above the roof, as shown, and is provided with a jacket 18 to prevent cold air cooling the warm air in the ventilator, and any suit: able cap 19 is locatediabove the opening.

It will thus be seen that the lower floor.v

containing the paper making apparatus as well as the finishing and cutting apparatus, is free from the warm air having moisture in suspension, consequently there is no soiling of the paper by dripping water ot' condensation.

By making the second floor shown, having the vertical open spaces 16 at each side, the foreman of the plant can stand at any point on the first Hoor and sce the paper passing through the drying apparatus, as the underside oi the drums are exposed, and he can also watch the 'torming apliaratus as well as thc finished product, as the two mechanisms 5and 18 are arranged close together. Furthcrn'iorc, hy locating the mechanism on the two loors, a comparatively short main driving shaft 2f) is required.

l-leretotore the making apparatus was at one end oi a long building and the finishing calendering rolls and cutter were at the opposite end, while the long drying mechanism was at the center, making it extremely diflicult to watch the progress of the paper through the machine, and this arrangement required the employment of a large number of men.

l have illustrated the machine in diagram, as the detail construction oi the sevcral mechanisms composing the machine -may be modified without departing from the essential features ot the invention.

I claim 1. paper-making apparatus having paper-forming and paper-drying mechanisms located at different levels, and a fioor separating said mechanisms, said floor having passages extending along the dryingmechanism and connecting with the space above and below the floor and permitting cooling' air currents from a lower level to pass into and ascend through the higher level containing the said drying-mechanism and to serve as a carrier ot the moist air arising from the latter.

continuous paper-making apparatus comprising the combination ot' a papermaking mechanism. a paper-drying mechanism. a paper-finishing mechanism, and a fioor intervening between the paper-making and Wiper-drying mechanism, said floor locating the paper-drying mechanisnl above thc paper-making mechanism, and being transversely discontinuous along substantially thc length oi the drying mechanism to permit 'fresh air currents from a lower lcvcl to ascend through the `level containing thc drying-mechanism and carry with them the moist air arising Jfrom the said ilryiiig-mechanism.

2i. rl`he combination in a ramer-making apparatus, of a building having two floors; paper-making mechanism and calcndering rolls and cutters on the lower floor; dryingmechanism extending substantially the iull length of the upper floor. the upper floor being mad(l in two levels so as to provide intermediate passages distributed along the ilrying-mcchanism ior air to risc from the lower floor to the upper floor; and means tor allowing thc moist air oi'l the upper floor to escape,

f-t. continuous paper-making apparatus having paper-forming mechanism and paper-finishing and cutting mechanism` including calcrnlering rolls on one level; drying-mccl'ianism located on a level above the other two mechanisms; a floor separating said mechanism; means for drawing ofi' the moist air rising from the paper passing through the drying merhanism, the finishing mechanism for the paper terminating at a point where the making mechanism hegins, so that an operator can see both the Carry off the moist air levels; a Hoor separating said meeheniems? said floor having air passages theieinne tending along the drying mechanism; and a series of ventilators at the roof of the upper Hoor in which the paper drying mechanism isloeated, so ne to cause en. air ein'- rent through the passages in the floor to from .the paper pass in ey through the drying mechanism.

6. The combination apparatus having peper'-'hii'niiiig and peper drying mechanisms located :it 'different in a. pepermeking l leveie; a Hoor separating said mechanisms, said Hoor having air passages therein extending along the drying mechanismand furnishing a communication between. Said levels; a series of heating pipes iocated in the ceiiing' of the room in. which the c'ii'ying mechanism is located; and e series of Ventilatore it the ceiling of said room so as to carry off the moist air passing from the drying apparatus.
